Like many other 2P!s, Hong Kong has multiple (a.k.a two) differing portrayals.

Unlike his counterpart, 2p! Hong Kong tends to show a lot of emotion. He is usually always seen with a smile, sometimes because he wants to forget about his harsh past. He is extremely lovable, and like 2p! England, loves to make people smile. 2p! Hong Kong is selfless, and doesn't want people to feel like how he felt in the past. He can be timid at first, but when you get to meet him, he is a huge chatterbox and a jokester. 2p! Hong Kong is also naïve. Even though his family is extremely cruel to him, 2p! Hong Kong still loves them. He can get intimidated easily, and he is a big crybaby. 2p! Hong Kong enjoys playing video games (usually fighting ones), eating, cooking, meeting new people, and cuddling.

2p! HK knows how to make cupcakes but he usually doesn't poison them. ...Usually. 2P! China nags him to get out of the house and become independent, but he won't budge. He sees 2P! Taiwan as his best friend.

It is common for 2P!s to be portrayed as murderous, psychopathic and possibly insane. To most, they are a darker version of the original Nations. However, because the Original Nations can be portrayed the same way by the fandom, how much hold this has depends on the person making the story.

2P! Hong Kong does not have murderous traits interpreted in the fandom, other than poisoned cupcakes.
